Consumer Protection As responsible manufacturers we take care to make sure that our products are designed and constructed to meet the required safety standards when properly installed and used. IMPORTANT NOTICE: PLEASE READ THE ACCOMPANYING WARRANTY Any alteration that is not approved by AGA could invalidate the approval of the appliance, operation of the warranty and could affect your statutory rights. Health & Safety This appliance may contain some of the materials that are indicated. It is the Users/Installers responsibility to ensure that the necessary protective clothing is worn when handling where applicable. The pertinent parts that contain any of the listed materials that could be interpreted as being injurious to health and safety, see below for information. Firebricks, Fuel Beds, Artificial Fuels When handling use disposable gloves. Fire cement When handling use disposable gloves. Glues and Sealants Exercise caution - if these are still in liquid form use face mask and disposable gloves. Glass Yarn, Mineral Wool, Insulation Pads, Ceramic Fibre Maybe harmful if inhaled. May be irritating to skin, eyes, nose and throat. When handling avoid contact with skin or eyes. Use disposable gloves, face-masks and eye protection. After handling wash hands and other exposed parts. When disposing of the product, reduce dust with water spray, ensure that parts are securely wrapped. Kerosene and Gas Oil fuels (mineral oils) 1. The effect of mineral oils on the skin vary according to the duration of exposure. 2. The lighter fractions also remove the protective grease normally present on the surface of the skin. This renders the skin dry, liable to crack and more prone to damage caused by cuts and abrasions. 3. ‘Oil acne’ is recognised by the presence of skin rashes. The arms are most often affected but may occur where there is contact with oil or oily clothing. Seek medical attention for any rash. Avoid skin contact with mineral oil or clothing containing mineral oil. 4. Inhalation of mineral oil vapours must be avoided. Never fire the burner in the open air as unburnt oil vapours are likely to occur. 5. Use a suitable barrier cream which will give protection against mineral oil, lanolin based hand cream are usually very effective. 6. Never syphon mineral oil by mouth. If accidentally swallowed, call a doctor, do not induce vomiting. NOTE: SMOKE/SMELL EMITTED DURING INITIAL USAGE Some parts of the cooker have been coated with a light covering of protective oil. During initial operation of the cooker, this may cause smoke/smell to be emitted and is normal and not a fault with the appliance, it is therefore advisable to open doors and or windows to allow for ventilation. Lift the lids to prevent staining the linings.

INTRODUCTION

SERVICE SCHEDULE

To ensure the best performance from your Stanley Brandon. It should be serviced once a year, preferably at the start of the heating season.

Annual Service During annual service flexible oil lines, burner nozzles MUST BE CHANGED.

This appliance must be commissioned by an approved engineer.

WIRING: Ensure there is no damage or loose connections. This should be carried out by a competent engineer.

Failure to install and maintain the appliance correctly could lead to prosecution.

BURNER REMOVAL - for cleaning and inspection. CLEANING - Boiler heat exchanger, flueways, oven and hotplate flueways together with ceramic fibre burner chambers. BURNER SERVICING OIL PUMP SERVICING - Cleaning of fuel line strainer. RE-COMMISSIONING REPLACEMENT PARTS

An additional flueway and combustion chamber clean halfway through the heating season may be necessary in some cases. The Stanley Brandon cannot be serviced whilst hot, so both oven and boiler thermostats should be turned off on the evening before the service visit.

OVEN DOOR FIT - Both doors must be checked and adjusted if necessary to ensure the alignment with the door catch is correct, the keep is secure and the oven is sealed when the door is closed. Additional Flueway Clean It may be necessary in some installations to give the boiler flueways a clean out at the end of the heating season. This appliance MUST be serviced at regular 12 monthly intervals to optimise its safety, efficiency and performance.

Re-commissioning BLEED AIR FROM OIL SUPPLY Disconnect the flexible oil pipe line at the pump inlet, open the stop valve slowly and run off some of the oil into a receptacle to establish an air free supply to the pump. Remake the connection oil tight and leave valve open.

FIT PRESSURE GAUGE Remove the bleed screw from the manifold and fit an oil pressure gauge with R1/8 connection to check the pump output pressure.

SWITCH ON ELECTRICITY Set the boiler burner time clock to continuous and turn the boiler thermostat to maximum. The boiler burner should run on pre-purge for 7-15 seconds. With the ignition spark energised. The oil solenoid valve should open allowing the burner to fire.

PRESSURE PORT BLEED SCREW Fig. 19

Until all the air from the oil pump is flushed out there may be some flame instability, resulting in the burner locking out. This will be shown by the burner stopping and the illumination of the signal light in the reset button of the control box (See Fig. 19). IN THIS EVENT, WAIT AT LEAST ONE MINUTE, then press the re-set button to restart.

Fault Finding BURNER DOES NOT START Burners Check that the burner has not gone to lock-out. Causes of lock-out can be: z z z z z z z z

No ignition, ignition electrode incorrectly positioned, insulation cracked, spark generator fault. No oil supply. Poor combustion. Photo electric cell incorrectly positioned, cracked or needs cleaning. Live and Neutral connections reversed. Faulty control box. Faulty fire valve. Faulty relays.

REFER TO FLOW DIAGRAM FOR ELIMINATION PROCEDURE. General You can carry out some checks on the controls before you need to access the controls compartment behind the controls door. If only one of the burners is not running then the fault must be after the safety overheat thermostat. Conversely of both the burners are affected then the fault lies before the programmer connections. For access to individual controls refer to section Replacement Parts and for wiring continuity checks refer to Figs. 34 and 35 wiring diagrams. To check out the electrical wiring at the burners you will first have to access the burner chamber. Use the following procedure:1. 2. 3. 4.

Isolate the electrical power supply. Open up the bottom burner access door. Remove door and put in a safe place. Unscrew the 4 screws holding the inner panel in place and remove panel. Unscrew the 3 screws holding the louvered plinth in place and remove plinth.

The external mains connections are made to a terminal block situated in the front left-hand corner of the burner chamber. Re-connect the electrical supply and check that there is 230V power supply available across the mains input connection L & N on the terminal block, if not then check connecting leads, fuses and whether power is available at the mains plug.

Fault Finding Error Table In the next tables a description of the different errors is given Errors can be divided in two groups. Blocking errors will disappear when error is gone, and non-volatile locking errors can only be reset by the reset button. A blocking error is indicated with an ‘E’ prior to the error number.

Fault Finding Cooker Burner (DKO 970) Information system The information system communicates with the outside world using a LED (the used Flash-Code is similar to the Morse Code). The messages are optically transmitted by flashing appropriately a LED. Using an (optional) additional terminal the messages can be recorded and displayed in easily readable form. Programming sequence display The built-in microprocessor controls not only the programming sequence but the information system too. The individual phases of the programming sequence are displayed as Flash-Code. The following messages can be distinguished:-

Fig. 36

26

Fault Finding Cooker Burner (DKO 970) In case of failure the LED is permanently illuminated. Every 10 seconds the illumination is interrupted by a flash code which indicates the cause of the error. Therefore the following sequence is performed which is repeated as long as the unit is not reset. Sequence:

Stray Light Monitoring The stray light check is performed at the end of the pre-purge time for the duration as mentioned in the table of timings. Low-voltage protection at 220 / 240V (110 / 120V) nominal voltage The mains voltage has to be more than 187Veff (94Veff) in order to allow the unit to perform a start-up. The mains voltage is not only mentioned in the start-up phase but also permanently during operation. If the voltage drops below 187Veff (94Veff).
